摘要提出了一种将标准短路试验波形注入多通道任意波形发生器,来产生模拟实际的校准波形,进而对测量系统进行校准的方法。校准装置使用现场可编程门阵列(FPGA)、直接数字频率合成器(DDS)等器件。对装置的检定结果表明:在10Hz～200kHz频率范围内,输出频率、输出电压最大误差分别为2.1×10^-6、3×10^-3。重复输出10次,输出幅值的最大相对标准偏差为5.7×10^-4,1年内幅值变化的最大相对标准偏差为1.9×10^-4。通过将该装置用于实际高压短路试验测试系统的校准,验证了试验波形的噪声、零漂及带宽均会对测量系统的准确度产生显著影响。

Abstract：A method for injecting standard short-circuit test waveforms into a multi-channel arbitrary waveform generator to generate simulated actual calibration waveforms and then calibrating the measuring systems was proposed. A calibration device were developed using devices such as field programmable gate array (FPGA) and direct digital synthesizer (DDS). The verification results of the calibration device show that the maximum error of the output frequency and output voltage are 2.1×10^-6 and 3×10^-3 in the frequency range of 10Hz~200kHz. Repeated output 10 times, the maximum relative standard deviation of the output amplitude is 5.7×10^-4, and the maximum relative standard deviation of the amplitude change within 1 year is 1.9×10^-4. By using the device for calibration of the actual high voltage short-circuit test measuring system, it is verified that the noise, zero drift and bandwidth of the test waveform have a significant impact on the accuracy of the measuring system.
